I have broke my DSG gearbox
Rather than wheel spinning(like it does on normal roads) it seemed to grip more on the sticky tarmac an jerk & jump. I believe this did the damage.
The box worked ok chanching gears automatically but I had to force the very stiff gear shift.
I waited a week and booked into the local dealers, where fortunately after testing the box stuck in Park.
I now have a hire car (courtesey of VW) and am awaiting a newgear box...feeling very fortunate
